4.5.24 Samsung Update Deleted Most Gallery Pics

[KJSJAS]

This is the second time this  has happened. Samsung updated 4.5.24, and now almost all my gallery pictures are gone. 

I read past forums from clearing the Gallery's cache, restarting phone, Samsung files... can't restore any pics. Only 16 random pics remain and 7 albums. Help. So ticked.

Is your gallery syncing with Microsoft OneDrive? If so you should be able to see all your photos in there. If you've physically deleted your photos from the gallery, there's still a chance they'll be in the OneDrive trash bin, however there is a time limit before the bin gets emptied and they're gone forever.

Have you not backed up your pictures? I would suggest you do, rely on them just being on your phone is a risk as you found out.

Software crashes, phones get broken or stolen

I would suggest backing them up, Onedrive, Google photos or Amazon PRIME have unlimited back up too or get a NAS with backup capability, the choices are endless
